This takes a lot of explaining; I suggest you read the Wikipedia article on subtraction for a short overview, or look for the corresponding sections in an elementary school math book, for more details.
Change the whole number into an improper fraction with the same denominator as the fraction and then subtract accordingly
If you can subtract whole numbers you can subtract decimals. Forget about the decimal for a sec and subtract the numbers as if they were whole numbers. 2.5 -1.4 =1.1 hope this helps and if not yahoo usually has good examples.

When you subtract one number from another, the result is called the difference. What does your question mean? If by "when two whole numbers are subtracted" you mean that you subtract one whole number from the minuend, and then you subtract another whole number from the difference, then the answer you get is another difference. In effect, you have one minuend and two subtrahends.
